Maintaining the Boiler

Danger

Before cleaning the boiler, make sure the boiler is turned off and the power supply is disconnected. The boiler may remain hot for few minutes after it is turned off. Wait until the boiler has cooled down before cleaning to prevent burns.

Draining the Boiler

To drain the boiler:

1

Press the button to turn off the boiler.

2

Disconnect the power supply to the boiler.

3

Protecting the Boiler from

Freezing

Caution

• To protect the boiler from freezing, recommend the use of a direct vent exhaust and intake system. Ensure that the exhaust vent pipe and the air intake pipe are both connected directly from the collars on the top of the boiler to the outdoors. This type of vent system minimizes air movement within the boiler.

• Freezing damage usually occurs due to back-drafting caused by negative pressure in the building. This is not a manufacturing defect, and therefore, VESTA.DS will not warrant any damage due to freezing. The installer is responsible for ensuring that there is sufficient make-up air to avoid such a situation, and the owner is responsible for ensuring protection against freezing.

To protect the boiler from freezing, follow these guidelines:

• Do not unplug the power supply cord, except for routinemaintenance. The boiler has a freeze protection functionthat warms up the boiler. The freeze protection functionwill operate regardless of whether or not the front panel isturned on or off, as long as the power supply is still connected.

• If the power or gas supply must be disconnected for anextended period, drain the boiler.

• Protect and insulate all water pipes, including the condensatetrap drain line, from freezing.

• If the boiler will not be used for an extended period of time,drain the boiler.

Notice

If you suspect that the boiler is frozen, contact an authorized technician or licensed professional.

Maintenance Schedules

Caution

A qualified technician should inspect the boiler at the beginning of every heating season and/or when there is a problem.

Owner maintenance

Daily

• Check that the area where the boiler is installed is free of combustible/flammable material and air-contaminants.

• Visually inspect the exterior of the boiler.

Monthly

• Inspect the condensate trap and the PVC fittings.

• Visually inspect the piping (water and gas) for leaks.

• Visually inspect the vent piping for signs of leakage and blockage.

Every 6 months

• Inspect the piping (water and gas) for leaks.

• Inspect the vent piping for leakage and blockage.

• Test to make sure the pressure relief valve is operating properly.

Service technician maintenance

Periodically

• Inspect the interior of the boiler.

• Clean the condensate trap and fill with fresh water.

• Clean the air intake filter.

• Check for leaks (gas, water, flue, and condensate).

• Check the system pressure (gas, and water).

• Check ignition and flame rod.

• Check wiring connections.

Maintaining the Boiler 13

Caution

• Follow the service and maintenance procedures given throughout this manual and in component literature shipped with the boiler. Failure to perform the service and maintenance could result in damage to the boiler or system.

• Failure to follow the directions in this manual and component literature could result in severe personal injury, death, or substantial property damage.

• The boiler should be inspected annually only by a qualified service technician. In addition, the maintenance and care of the boiler must be performed to assure maximum boiler efficiency and reliability. Failure to service and maintain the boiler and system could result in equipment failure.

• Electrical shock hazard – Turn off power to the boiler before any service operation on the boiler except as noted otherwise in this instruction manual. Failure to turn off electrical power could result in electrical shock, causing severe personal injury or death.

Addressing the Reported Problems

• Inspect any problems reported by the owner and correct before proceeding.

Inspecting the Installation Area

1

Verify that boiler area is free of any combustible materials, gasoline and other flammable vapors and liquids.

2

Verify that air intake area is free of any of the contaminants listed in Installation Manual. If any of these are present in the boiler intake air vicinity, they must be removed.

If they cannot be removed, reinstall the air and vent lines per the Installation Manual.

Inspecting the Boiler Interior

1

Remove the front cover and inspect the interior of the boiler.

2

Vacuum any sediment from inside the boiler and components.

Remove any obstructions.

Cleaning the Condensate Trap

1

Inspect the condensate drain line, condensate fittings, and condensate trap.

2

Remove any sediment in the trap.

3

Fill with fresh water until the water begins to pour out of the drain

Checking all Piping for Leaks

Eliminate all system or boiler leaks. Continual fresh makeup water will reduce boiler life. Minerals can build up in sections, reducing heat transfer, overheating heat exchanger, and causing heat exchanger failure. Leaking water may also cause severe property damage.

1

Inspect all water and gas piping and verify to be leak free.

2

Look for signs of leaking lines and correct any problems found.

Checking the Flue Vent System and Air Piping

1

Visually inspect the entire flue gas venting system and air piping for blockage, deterioration or leakage. Repair any joints that show signs of leakage. Verify that air inlet pipe is connected and properly sealed (if installed).

2

Verify that boiler vent discharge and air intake are clean and free of obstructions.

Caution

Failure to inspect for the above conditions and have them repaired can result in severe personal injury or death.

Troubleshooting

Basic Problems

If there is a problem with the boiler, refer to the following table for possible remedies. For minor problems, turning the boiler off and then turning back on may resolve the situation. If turning the boiler of and on and attempting the remedies suggested below do not resolve the problem, contact an authorized technician, licensed professional, or technical support at 1-800-761-0053.

• Is the water temperature setting appropriate?

• Even though the unit may be operating properly, the cold water contained in the piping will need to fow through the faucet before the hot water can reach the faucet. Wait for several minutes.

• If the cold water supply temperature is too high, it is possible for the temperature to be higher than the temperature set on the front panel. Decrease the water temperature on the front panel.

• If only a small amount of hot water is required, it is possible for the temperature to be higher than the temperature set on the front panel. Decrease the water temperature on the front panel.

• If the cold water supply passes through a solar preheating system, it passes for the delivered water temperature to be higher than the temperature set on the front panel.

The water is not hot enough.

• Are the gas and cold water supply valves fully open?

• Is the water temperature setting correct?

• Fully open the gas and cold water supply valves.
